So, how you gem your gear is pretty important.

You sir, are a master linguist.

I know, right? I should get paid for this.

Anyway, one of the things you have to take into consideration when gemming your gear is socket bonuses. When should you go for them? Often times a spreadsheet is your best answer to theses and many other DPS questions but I’m going to take a minute and show you how to quickly eyeball a piece of gear and make an intelligent decision.

A quick disclaimer first: The most important thing when gemming is to make sure your Meta-Gem stays active. Which for rogues, will require at least 1 red, yellow and blue gem and you should use take the opportunity to kill two birds with one gem (rim-shot) and grab a socket bonus while activating your meta whenever possible.

For this discussion I will be using the following gems to fill the various slots.

The method of calculation (quick secret, it’s addition) is the same when using other gems but for simplicity I will be using these. It should be noted that when ignoring socket bonuses you will simply be stacking the red gem of your choice (Agi, Arpen, or AP)

Now, let’s look a two pieces of gear, one of which I suggest ignoring the socket bonus and the other I suggest going for the socket bonus. Let’s find out why.

Cuirass of Calamitous Fate – 1 Yellow Socket, 1 Blue Socket, +12 AP Socket Bonus

If you go for the socket bonus:
+20 Agi, +10 Crit Rating, +15 Stam, +12 AP

If you ignore the socket bonus:
+40 Agi

So, the question is really:
+20 Agi vs +10 Crit Rating and +12 AP

So, what’s the answer? Well, 20 Agi will give you 20 AP. So far, no socket bonus is winning but what about the 10 Crit rating? How does that stack up to the 20 Agility. Not too well actually.

83.33 Agi ~= 1% Crit Chance
45.91 Crit Rating ~= 1% Crit Chance

Therefor:

20 Agi ~= .24% Crit Chance
10 Crit Rating ~= .21% Crit Chance

The quick and dirty math:

83.33x = 1; x = 1/83.33; x = 0.012
20x = y; 20(0.012) = y; y = 0.24

With that known, the abstract question of which is better:
+20 Agi vs +10 Crit Rating and +12 AP
Is actually, which is better:
+20 AP and .24% Crit Chance vs +12 AP and .21% Crit change

That’s an easy, apples to apples comparison and you can easily see that not going for the socket bonus wins. Keep in mind you don’t have to do this math every time, once you know the basics you can pretty much eyeball it (do the math to double check if you’re unsure).

Conqueror’s Terrorblade Legplates – 1 Red Socket, 1 Yellow Socket, +6 Agi Socket Bonus

If you go for the socket bonus:
+36 Agi, +10 Crit Rating

If you ignore the socket bonus:
+40 Agi

So, the question is really:
+4 Agi vs +10 Crit Rating

Using the above math:

4 Agi ~= .04% Crit Chance
10 Crit Rating ~= .21% Crit Chance

So:
+4 Agi vs +10 Crit Rating
Becomes:
+4 AP and .04% Crit Chance vs .21% Crit Chance

To me, the socket bonus is an easy win here.

So that’s socketing in a nutshell. Isn’t math grand?

Happy Socketing!

  1. how can you have 40 agi? im assuming you’re putting the 20 agi cardinal gems but I was under the impression that you can’t put a red gem in a yellow socket….

  2. @tedoubledy
    You can put any gem in any socket. Matching color just gets you the socket bonus

  3. ………………………………………
    i want to cry.

    Im such a nooblet

  4. If you’re only matching one Blue socket I would suggest using the Nightmare Tear (+10 to all stats) instead of a Shifting Dreadstone as it’s the same amount of Agi, 10 Sta instead of 12 and 10 Str (AP) It’s prismatic so it would count for whatever color slot you put it in.

    So for the first Blue slot you’re looking at filling in your example of +20 AP and .24% Crit Chance vs +12 AP and .21% Crit change above actually would ammount to
    +20 AP and .24% Crit Chance vs +22 AP and .21% Crit change
    or .24Crit vs .21 crit and 2AP (and given that you need 1 Blue gem to activate the meta…)
    However for any second blue slots that example works

  5. Zaltu!!
    Great site bud.

    Wouldn’t the Nightmare Tear be a smidge better to use to satisfy blue Meta requirement?

  6. You can put any colour gem in any colour socket, but doing so you may loose the socket bonus.

  7. Yea. In your 1st example pure dps stats do come out ahead if you skip the bonus. But, nobody factors in poor little stamina ;( You gotta give stam at least a tiny bit of credit. Sometimes that extra stam you get from your purple gems can be valuable and play a factor. Even the best rogues flirt with death sometimes before getting that nice heal.

  8. CANT DPS IF YOU DIE. Let me clarify, Being dumb and taking a direct hit via whirlwind or standing in fire =’s dead reguardless of how much stam you have. But, if for some reason your taking damage that you cant avoid and you cant wait for that next heal commin your way then extra stam will show value. Fights dont always go perfect. Healers do get distracted sometimes, or lag.
